METHOD AND MACHlINE FOR ASSEMBLING AND, UNITING FRAME MEMBER S.

Application filed March 18, 1925. SeriaLN'o. 16,582.

which finally bring about an improved method for uniting said framesaround the edge of the center medium. When em ployed for installingcurtain windows, my machine not only mounts complementary grommet-likeframe members upon theop-' posite faces of the curtain or other'carryingmaterial, but is further capable of uniting said frames. and binding theinner border a plurality of the curtain about the marginal edge of thecenter medium to make a Weather proof joint therewith.

In the specific-embodiment herein disclosed, my machine is shown asequipt with i of separate interconnected. crimping tools which areadapted to be introduced as a unit into asuitably shaped hollow groovedexpansible male sheet metal frame member subsequent to its assembly intoa nestled co -acting'female frame memher, and by the operation of saidtools, simultaneously indenting or crimping said male member intointerlocking engagement with the female member at plurality of spacedpointsv disposed longitudinally of said'members. The use of my improvedmachine serves to eliminate the need for individually. indenting crimpcleats between said male and female frame members or for otherwiseseparately drawing up a number of spaced screws, staples, prongs orother fastening devices when used for uniting complementary framemembers.

Said machine is particularly adapted to interlock twopart window sashframemembcrs, such as are commonly employed to bind a sight pane into anautomobile curtain, side panels or the'like which may be fashioned fromleather, fabrics, fibre board or similar ,carrying material. As appliedto vehicle curtain lights and especially back curtain sights, a set ofcomplementaryframe members are preferably disposed on opposite sides ofthe pane or other centerv proof. binder between the pane and itssurrounding curtain fabric or carrying material.

The primary object of this invention is to provide for a simple andeffective machine and method capable offacilitating. the rapid andeconomical installation of curtain Window assemblies to thus fully meetpres: ent day production needs in the automotive industry. .Toaccomplish this end, I preferably use a conventional press but equip itstraveling ram with frame uniting means which in the present instancecomprise a pluralityof crimping tools each, rotatably mounted oninterconnected spindles, and by imparting an oscillatory movement tosaid tools, I simultaneously. indent a series'of spaced crimp cleatsbetween the assembled male and female frame members and thereby minimizethe time and cost of. mounting curtain light frames when assembled on aproductive scale; It is pointed out that the present invention isdirected toward suitable mechanism designed to attain this end and doesnot lay claim to the indicated interlocking process per se.

Embodied herein are also other features of structure and method stepswhich insure the desired rapid and proper binding of other external theframe and its pane into the curtain, all

of which will be set forth in detail herein' after. N I

Fig. 18 is a plan view of the frame keeper piece while Fig. 19 shows across-section of same as taken along line 1919 of Fig. 18. Referringfirst to- Fig. 1, this represents a suit-able hand-operated uprightpress of the conventional G frame type which in its 'entirety isdesignated by the letter A. The frame proper A may be provided with arelatively short vertical guide Way A in which is slidably mounted atraveling head or ram A; adapted to overrun the lower transverse face ofsaid guide. The ram may further be equipt with a suitably disposedbalance lever A carrying the counterweight A The lower leg of said'framehas a foot flange A and this may be fashioned into the relatively longplatin A disposed trans versely to the vertical plane of the frameproper. Said platin is suitably spaced with respect to said lowertransverse face. of the guide A to constitute a frame gap therebetween.Superimposed upon the topface of said platin is a cover plate or dieblock A equipt with shallow endless groove or recess A adapted toreceiveand seat the female member of the two part sheet-metal curtain lightframe. 1 It is pointed out that said die block A serves essentially inthe capacity of an abutment adapted to oppose the thrust abutment meansis not intended to be specifically directed toward the structuralfeatures shown in the drawings but broadly comprises any similar orequivalent element that might serve the indicated purposes.

Attached to thelower or bottom face of the ram A is a transverselydisposed retaining plate A which is adapted to travel with J plate maybe equipt with complementary 0 A each provided with plus adapted to e'ngage therespective links A and A The upper free end of said linkspivotally engage the spaced lever arms A and A, re-

spectively, and these arms are tied together by the lever oke A and-turnabout the fulcrum shaft Said yoke is provided with a manipulating handleA and it will be apparent that when said handle is moved from itsvertical or normalposition shown shown correspondingly shift the slidinram A and its retainin plate A,, from t e'ir outmost position wit'respect to the block into the evises such as p by means of screws suchas B as shown in Fig. '7. F rcely mounted within said slot B is a rackslide or reciprocating clement B and this may be actuated by means ofthe shifter lever B As indicated, this lever may he of the bel cranktype fulcrumed on an extended portion of one of the side flanges andadapted to be raised and low ered therewith.

One leg of said lever is equipt with a shifting handle B while its otherleg is proyided with a projecting pin B adapted to engage a suitableslot B by means of which the slide or element B. may be shiftedlaterally between its full and its dotted positions indicated in Fig. 5.

i forming or crimping tool spindle B equipt with a shank B -having anenlarged actuatmg gear segment B wh1ch latter member may be fitted intoany one of said counterbores and supported by its shoulder such as B Theshank B maybe recessed into a socket for receiving the crimping tool Cand this may be locked in place by the set screw B The referred type ofcrimping tool is shown in detail by Figs. 3 3 and 3. The tool proper hasa flattened shank portionC adapted to fit into'the respective recessedspindle shank B This tool is further provided with a reduced neckportion G while its free end is equipt with a head element comprisingoppositely disposed beveled toes C and (1 respectively. As shown in Fig.

3 the overall length Z of the oblong head is made greater than itswidth-dimension 7), while the height it is made relatively short forreasonsthat will appear hereinafter.

As will be understood, the spindles B together with their inserted toolsare intended to oscillate freely within their respective mountings. Inorder to simultaneously operate all the spindles, the slide orreciprocating element B is preferably equipt with a series of inset racksegments such as B which are adjustably secured to the edges of saidslide so as to properly engage the respective spindle gear segments suchas B 3, and simultaneously impart. a rotary movement to the aligned toolheads when ever the lever B is shifted within the prescribed limits oftravel. If desired, any number of additional tool-spindles may besimilarly mounted andas will be apparent from Fig. 5', certain of thesespindles may be located adjacent to the transverse ends of the spindleholding means B by suitably slotting the rack slide at B as indicated.The spindle disposition is preferably such, that the elongated head ofthe respective crimpingtools C will align in such fashion that theymayreadily enter the mouth of 86 an endless expansible groove part formedin the male member of the curtain light frame. V 1

1t willbe further observed that the relatively long spindle shank Bprojects considerably be ow the; bottom face of either side flange B andB Intermediate certain of the respective spindles and extending a littlebelow the extremities of said cr1mping tools a series of insertedupright bridge strips B depend from the spindle holder B The spacedstrips are intended to freely enter and align with the mouth of saidexpansible groove part of the male frame member and tightly thrustsaidgroove into close engagement with its co -acting female framememberprior to interlocking the frame members together. The bridge strips Bbe-' ing slightly longer than the extremities of the tools C, serve toprotect said tools against any direct thrust which the manipulatinghandle might otherwise exert thereon.'

Referring further to the spindle holder B this is equipt with a flatpressure pad 110 the opening through which is preferably but notnecessarily disposed to encircle the downward projecting portions of thevarious spindle shanks B and this opening is made sufficiently large toencompass 115 the perimeter of the complementary nestled frames and abutthe block A so as to snugly hold down the interposed fabric surroundingsaid perimeter and prevent wrinkling thereof, as shown. The bottom faceof the pressure'pad is mounted to fall somewhat pressure pad is designed:to be resiliently hung with respect to holder 13 by means of a seriesof adjustable screws such as B shown in F 12, which screws are threadedin registering holes suitably disposed in,

the pad B,,. The enlarged head of said screws may besu ported upon acountersunk shoulder B formed in the spindle holder as shown, while thelower portion of the screw holes maybe recessed to re' 1 .ceive thespiral springs such as B which thrust against the pressure pad and serveto 'yieldinglyholcl samein an adjusted spaced relation with respect tothe holder B As a further refinement in design, .at

'tention is directed to the shouldered tit f snap means 13,, of whichseveral maybe pgtsition by compressingthe thrust springs mounted in theside or end walls of the-pres sure pad. Thesetits slightly project'Iinto:the hollow, space formed in said pad. B and'may be snapped backo-uttheir normal As is best shown in Fig. 10, the purpose of "these titsis to hold up the male frame member. in its suspended position prior toperforming the indicated cleating operation, said tits serving in thecapacity of gripping means for manipulating one-of 3 Taking up now thepurpose of my machine as more specifically applied to the cleatingofcurtain light products, this will be made clear by further referenceto. the

structural details pertaining to the sheet metal frame members that areto be' united about the edge of a pane or other suitable center medium.:As disclosed by Figs. '13 to 19, the letter-D representsjin itsentirety anendless outer frame member, while E is the transparent sightpane mounted therein. The frame D may be provided with acrosssectionally V dishedshaped offsethaving complementary intu'rnedmarginalflanges forming an annular undercut receiving slot Dth'erbetween which -is preferably disposed around the contour of saidpane to constitute the female part of said vframe.

In the present window assembly the curtain fabric F is intended to liealong'the "parting face of outer frame. .D-as defined by said inturnedflanges. The pane E is I centrally disposed and spans the innermost of.the int-urued flanges and is preferably cushioned by the interposed"fabric F in the manner indicated in Fig. 10. The opposite .marginal"face of ,,-the pane E may. be grippedby aspecially shaped inner orbackmg frame and this male member of the two-part frame 15 designatedasa whole by I the letter G. i i This inner sheet metal frame comprisesa bead-like pane engaging flange G which need not however be madeendless as are the remaining parts of'this member; said flange ispreferably but not necessarily cut away along one of the frame" sidesand terminates in the respective socket parts G and G thus forming a gaptherebetween.

The inner frame G is further provided with a relatively narrow groovedmale part Gr comprising side walls G and Gr which are disposedsubstantially normal to the face of the pane and tied together by theintegral Ttransverse wall Gr serving to close the bottom of said groove;The proper overall face dimension of this bottom wall is determined bywidth of the female part or receiving vslotD, of the outer frame, theintent being that said trough shaped grooved male part shall registerwith and be adapted to enter any desired shape that may be given to theslotted female part.

When completely assembled upon the curtain fabric, the two co-actingframe membersapplied to acurtain window installation are finally broughtinto the. relation indicated in Fig. 14.. Prior to interlocking saidmembers D and G, they are firmly sprung together thus interlacing andmak mg the curtain fabric take a circuitous path about the nested maleand female part in the manner illustrated by Fig. 16.

While in this stramed or sprung relation, the male and female. framemembers may be w interlocked by means of the described crimping tool.The width ,b of the tool-toes is made somewhat smaller than the spacingbetween the side walls Gr and (3: of the grooved male member whilethelength Z of said tool is made somewhat larger, to the-end that when apartial turn is given to the.

shankC of the inserted tool subsequent to the assembling of the membersD and G, thiswill cause said to simultaneously indent or forcibly expandthe side walls; if v preferred, the use of a greater toe pitch Z willserve to. cut through said sidewalls and thus form up projectingear-like spurs which interlock' with the undercut edges of the describedfemale frame member D.

Either alternative-indenture of said male part of the frame G may beresorted-to and 1t willbe seen that its overall width is now greaterthan that of the female slot D so as to positively interlock said frametogether.

' It will be apparent that this cleating operation also securely bindsthe interposed cur-y tainfabric to the assembled frame and the use of aplurality of spaced cleats for unit- .ing the frame members insuresag'ainstpulling the curtain border out of its binding.

Subsequent to interlocking the assembled frame members about the pane asdescribed,

the pane may thereupon stlll be conveniently slid out from between thespaced innermost flanges of the framemembers through said gap in thepane engaging flangeG As detailed in Fi 18 and 19, a keeper piece G maybe emp oyed tospan said gap and hol Tthe pane in placeand this piece maybe equipped with short projecting tongues G,

sition shown in Fig. 1, and that the tool car' rier is equipped with thedescribed, appurtenances,'then the press is readyto' receive thecomplementary frames in the fashion indicated in Fig. 10. That is tosay, as a first step in my method of installing a curtain window, theouter frame or female member .D is seated in the recess of the die blockA while the inner frame or male member G is lodged into the pressure padB and detachably suspended therein over the various snap tits'B inalinement with the seated frame D as showni As a' second step, thecurtain F together with the pane E is introduced between said separatedframe members and these inserted parts are mounted upon the seatedcomplementary frame parts preferably in superimposed relation as shownin Fig. 10.

' As a third step the lever A is pulled down into its lower position asshown in dotted lines by "Fig. 1, andth-is'will cause the carrier andits suspended male member j G to be lowered into the assembled relationshown by Fig. 11. The fabric thereby becomes interwoven-between thenestled male part (hand its co-actin undercut female slot D and byfurther pu ling down on said lever, any augmented thrust on the ram willcause the bridge strips to snugly press and hold the two frame membersinclose engagement preparatory to cleating theframes into interlocking.relation- It will be apparent that the pad B will at. the same time havebeen pressed 'up-closertoward the spindle holder B 'and that thepressure pad is made to thrust down upon the fabric around the entireperimeter of said'nestled frames.

\Vhile held in this strained relation, the

r shifter lever B is drawn laterally into the dotted position shown inFig. 5, which in turn simultaneously partially rotates the various tooltoes and this serves to indent or crimp spaced interlocking" cleatsbetween themale and female parts of the c'o-acting frame D and G andthis feature constitutes the.

fourth step in my method.

The lever B isnow again placed into-its raised or lowered as described,the free end.

normal or full-lined position which then permits the unhamperedwithdrawal-of the tool carrier and its associated parts from theupturned mouth of the grooved male frame part G Thereuponthemanipulating lever A may be raised into it's normal or vertical positionwhich then completes the cleating operation as performed by my machineand allows the curtain together with its installed frame and pane to beremoved as a unit from the abutment block..

In certain cases especially when a sight pane is'to be installed intothe conventional fabric curtain, it is preferred to introduce suchfabric between the complementary frame members in an uncut condition asre gardsthe sight opening, although itmay be expedient to cut crossslits 1n sald pane span- .ning curtain portion for the urpose ofaugmenting its take up and facilitating the described interlaced bindingof the inner fabric border into the frame members, all without drawinginwardly or wrinkling that portion 9f fabric lying outside of the frameperimeter. After otherwise completing the frame assembly in the press,the curtain fabric when left to span'the pane, may thereupon be trimmedto make the curtain opening conform to the inner contour of the frameand thus remove obstruction to the normal transparency of the pane, andwhen resorted to, such trimming operation consti-.

tutes a final supplementary step in my method of installing curtainlights.

It will be apparent that the removable keeper piece G may, now beinserted-in place, but this feature does notconstitute any essentialstep in the described installation method since said keeper is primarilyprovided for pane renewal purposes. In the event that the use of mymachine should be confined to mounting and uniting moulding-likecomplementar edge of a center medium, it will be understood thatthe'necessa-ry installationsteps will be substantially similar to thoseheretofore set forth except in so far as the omission of the insertedcurtain element may frames about the modify or-simplify the describedoperations. I

Supplemental means are also provided to facilitate the proper operation,of the machine, and to this end a lock device maybe used such as isshown in Figs.'8 and 9. This lock feature comprises an upwardlyprojecting stanchion H the lower end of which is set into. or otherwisesecured to the rack slide B and adapted to move therewith throughasuitableclearance hole cut in the retaining plate A One edge of thestanchion is dis posed to' move alongside the upright face of the ramguide housing as shown in Fig. 10- by dottedlines andin such fashionthat.

said stanchion is made to cooperate with an L-shaped obstruction. Whilethe manipulating handle A is of saidstanchion is obliged to ride;alongside said housing face and this serves as a stop device to preventinadvertentl moving the shifter lever B out of'its fullined positionshown in Fi 5. This stop device maintains the desired initial ali nment'on part of the various oblon crimping tool heads so as to,

prevent any a lique turning thereof until the assembled male and femaleframe members have been firmly pressed together and 'are ready for thedescribed crimpingoperation.

As soon however as the carrier tool "a .pliances have been properlyentered into t e a frame groove G, as'indicated in Fig. 11, the

free extremity of the stanchion will then have been sufficiently loweredto pass under the bottomtransvers'e edge of said guide housing andthereafter allow the shifter lever B to move the rack slideB into itscross-sectional position indicated in Fi 9. In the meantime, the headsof the crimpto indent a-crimp cleat between theassembled frame members Dand G. While in said .oblique position, the respective tool-heads maynot be raised without .tearin outthe frame parts and it is the furtherfunction ofv my interlockingdevice to prevent damage on this account'lAslongtherefOre as said stanehion'rides' under the bottom hous ingwall, the shifterlever B, is operative,

Furthermore itis not. essentialythat the curtain .be ,fash ioned from fabric and likeflexible materials I I clear the nest but the manipulating handle Acannot be raised until the shifter lever is brought back into itsnorinal position in; which the tool heads align with said frame grooveand are able therefrom. a I My machine is likewiseapplicable to unit:

It'wi'll also beunderstood that variouschanges in the details of my machine may be "resorted to such as makingsame elike, andthat while 'the described species of frame unitingmeansrepresents what is now considered f a preferred embodi- -ment ofmy'machipe the result attained -might be alent. meth dgggicated by-.substantially equiv- --heretfore escribed. an
